ISTC's Technical Assistance Program engineers and their partners at the Illinois Manufacturing Excellence Center, Energy Resources Group, and IL-Solar, Inc. conducted an assessment at BEER NUTS, a nut roasting facility in Central Illinois. They found that a rooftop solar PV installation would put the company on the path to achieving net zero electricity. On-site solar yields cost savings, environmental leadership and competitive advantage, and is a technology that can be implemented in most manufacturing facilities.
